Patent DE-3409953-A1 (DE)
Title: Process for the preparation of electroconductive and/or thermally conductive plastics
Inventor: HOLL WALTER DR
IPC: H01B1/22
Filed: 1984-03-17
Abstract: A process is proposed which serves for the preparation of electroconductive and/or thermally conductive plastics which contain a conductive component and are preferably processed by injection moulding or transfer moulding. The majority of the plastics serving as the matrix material has a higher molecular weight than the smaller part which remains and is first converted to the particle size desired in the finished structure. Then either this majority of the matrix material is coated with the conductive component and the smaller part of the matrix material having a lower molecular weight is admixed as a fine powder, or the conductive component and the smaller part of the matrix material are premixed and jointly applied to the surface of the coarser parts of the majority of the matrix material. The majority of the matrix material is present in an amount of 80-85% by volume, and the conductive component in an amount of 5-10% by volume and the smaller part of the low-molecular-weight matrix material in an amount of about 10% by volume. The material prepared in this way can either be directly injection moulded, transfer moulded or metered through nozzles in dispensers, or it can be regranulated before further processing.

Patent DE-3503204-A1 (DE)
Title: Method and device for controlling the chromaticity on the surface of a body
Inventor: WILMOWSKY HANS-JUERGEN VON DR
IPC: G01J3/46
Filed: 1985-01-31
Abstract: The subject-matter of the invention is a method for generating colour content signals with the aid of which the chromaticity of a surface region of an object can be detected independently of fluctuations in illumination. Radiation emanating from a surface region (1) of the object (2) is decomposed by filtering into three colour contents, which are converted into electrical colour content signals. The colour content signals are combined to form an aggregate signal which, as actual value of a controlled variable, is compared with an adjustable desired value in order to form a system deviation. The magnitude of all three colour content signals is modified to the same extent in accordance with the system deviation for the purpose of reducing the system deviation to zero or to a very low value. At least one colour content signal is multiplied by a coefficient which corresponds to the quotient formed from the colour content signal and the magnitude of the parameter for a prescribed desired value with which the product of the colour content signal and coefficient is compared in order to form a system deviation. The magnitude of the parameter is modified for the purpose of reducing the system deviation to zero or to a value close to zero. <IMAGE>

Title: Gas-cooled nuclear reactor
Inventor: WILKIE DAVID
IPC: G21C3/12
Filed: 1985-12-06
Abstract: The graphite sleeves of a fuel bundle in a gas-cooled nuclear reactor are constructed with a web/groove profile on their outer surface, in order to increase the resistance with respect to the flow through an annular channel between the fuel bundle and the sealing bore of a channel during raising or lowering of the fuel bundle out of the reactor core or into the same. The web construction can extend in a multiple-threaded fashion in the shape of a helix about each sleeve, and can have an asymmetric profile, so that the resistance with respect to the coolant flow is less when the fuel bundle is in its final position in the reactor core than when the fuel bundle is raised or lowered.
